Empty Spaces In File Name

This issue is what brang me to this forum:
Calling OFFLINE files from HTML webpage on local drive using window.setTimeOut to delay most calls. ISSUE: When I call a file w/o empty space in name, this function calls w/o error on page, but I do not know how to do it when file contains empty space(s) in its name.

HTML Code:

function runXZNNespritsPMz()
{
File="E:\\XZNNesprits\\ZZ XZNNesprits PMz.session";
//can only launch such a file when no empty space present in name
WSH=new ActiveXObject("WScript.Shell");
WSH.run(File);
}

How do I correctly write the full path of such a file containing empty spaces in its name?

Thanks so much SaswatPadhi. You are the first one who ever answered me a question on this forum (my first ever too!). OK I calm down.

I tried your syntax as a var value and it is perfect in js except that there must not be present those two backslashes in between the double double quotes. So that would be:

var whichever_name = '"E:\\XZNNesprits\\ZZ XZNNesprits PMz.session"'

In fact, I started to relocate many of the files and folders I needed to call through js (renaming them without any empty spaces) and found that when you look at the Properties, in WinXP, of a shortcut, it give you the target path embedded by double quotes, and, if no empty spaces in name of file nor of the whole path, it does not embed it in double quotes.

I found an error in my syntax. It really goes like this and I think it is completely legal (someone would need to confirm this though)(many people coding embedded js into HTML like to use single quotation for js related syntax and double quotation for HTML). So the correct and flawlessly performing (no errors on page within IE) syntax for my example is:
